Abstract

L'invention concerne un appareil d'alimentation électrique, un dispositif d'éclairage en contre-jour et un appareil d'affichage à cristaux liquides comprenant cet appareil et ce dispositif. Une section de commande permet de produire un signal de commutation de manière à commander une sortie d'un courant constant acheminé jusqu'à une unité de lampe en réponse à des signaux de marche et/ou d'arrêt et à un signal de mise en veilleuse, et une section de commutation permet de commander une sortie d'une source de tension de courant continu en réponse au signal de commutation. Une section d'émission de courant fournit à l'unité de lampe une source de tension de courant alternatif dotée d'une tension constante. Une section de détection permet de détecter une variation d'un courant acheminé jusqu'à l'unité de lampe et une section de détection permet de comparer un signal de détection avec un signal de référence prédéterminé afin de produire un signal de détection destiné à la section de commande, ce qui permet de maintenir le courant constant à acheminer jusqu'à l'unité de lampe. Par conséquent, cet appareil d'affichage à cristaux liquides peut prévenir la détérioration d'une image et les dommages d'un circuit correspondant.
